#
# rc.d script for the vrobbler high-priority Celery worker.
#
# PROVIDE: vrobbler_celery_priority
# REQUIRE: NETWORKING postgresql redis
# KEYWORD: shutdown
#
# Installation (on the FreeBSD jail):
#
#   install -m 0555 rc.d/vrobbler_celery_priority /usr/local/etc/rc.d/vrobbler_celery_priority
#   sysrc vrobbler_celery_priority_enable="YES"
#   service vrobbler_celery_priority start
#
# Configuration (via sysrc or /etc/rc.conf):
#
#   vrobbler_celery_priority_queues  - queues to consume  (default: priority)
#   vrobbler_celery_priority_bin     - path to celery     (default: /usr/local/bin/celery)
#   vrobbler_celery_priority_flags   - extra daemon(8) flags
#
# Consumes the "priority" queue where interactive/user-facing tasks (agent
# session prompts, Mopidy queue adds, favorites, reverse geocoding) are routed.
# Higher concurrency with a small prefetch keeps these tasks snappy even when
# the default and background workers are busy. The nodename is fixed to
# priority@<hostname> so it can coexist with the other workers on one host.
